Title: Improvements in carburetters for internal combustion engines
IPC: F02M31/08
Filed: 1919-04-29
Abstract: 149,036. Byrom, J. April 29, 1919. Dash-pots.-Relates to carburettors for internalcombustion engines of the kind claimed in Specification 13370/11, [Class 7 (iii), Internal-combustion engines, Carburetting-apparatus &c. for], in which the fuel supply is governed by a suction-operated needle valve so that, as the engine speed increases, the fuel supply is diminished and vice versa. The invention includes special constructions of the bellows or dashpot employed in the suction-operated governor mechanism for controlling the fuel jet. In the form shown in Fig. 1, the spring-controlled needle valve 6 moving in the fuel nozzle 2 is operated by a rod 7 depending from the movable cylinder 20 of an oil dash-pot mounted in a casing 8. The upper part of the rod 7 engages a spring-controlled stop 22, the spring of which is adjustable by a screw 24, the downward movements of the stop being restricted by a nut 26 adjustable from the dash-board. The fixed piston 18 of the dash-pot, the upper part 13 of which contains oil, communicates with the induction pipe by a passage 9, and with the interior of the cylinder 20 by passages 16, 17. When the engine suction increases, the cylinder 20 and rod 7 rise and permit the needle valve 6 to reduce the fuel supply. Fig. 3 shows a bellows arrangement in place of the dash-pot. The hollow bellows element 29, which is attached to the rod 7 by a collar 34, is formed of a number of sheet metal disks 30 connected by inner flanges 31 and outer flanges 32, these flanges being soldered together. The interior of the bellows communicates with an oil chamber 14<a> by passages 33, and the chamber 14<a> leads to the induction pipe by a passage 9<a>.

Title: Improvements in or relating to apparatus for coating tubular fluorescent lamps
IPC: H01J9/22
Filed: 1951-05-07
Abstract: <PICT:0697999/III/1> Apparatus for coating the interior of tubular electric discharge lamp envelopes with fluorescent material suspended in a liquid, comprises means for holding a tubular envelope inclined both to the horizontal and vertical, means for introducing a quantity of the suspension into the higher end of the tube, and means for rotating the tube about its axis whilst the suspension flows down the tube.  Tubes 1 are carried on a continuously moving conveyer 2 consisting of two endless belts 3 carrying between them a plurality of vertical wooden battens 4, having metal brackets 7 on which the lower ends of the tubes rest, and spring clips 8 which grip the tubes near their top ends.  At the coating stage the top of a tube is withdrawn from the clip 8 and the tube laid on rubber rollers 11, one of which is driven by a motor (not shown).  A third roller 12 is lowered about a pivot rod 15 to hold the tube in position, and the tube rotated about its axis.  Coating suspension is contained in a constant head reservoir 9, to which it is fed by a pump as described in Specification 697,998.  A valve is opened for a suitable time to allow the suspension to flow through a flexible pipe 10 and a discharge tube 16 into the rotating tube 1, which is thus evenly coated.  Excess suspension drains into a trough 5.  As the coating proceeds the rollers supporting the tube 1 and the discharge tube 16 move with the conveyer.  When the coating is completed the flow of suspension stops, the tube is stopped rotating, the roller 12 is raised, and the tube replaced in the vertical position in the conveyer.  The rollers and the discharge tube 16 then return to their original position.  The operations may be performed mechanically or manually.

Title: Improvements in firearms
IPC: F41A1/08
Filed: 1968-03-06
Abstract: 1,213,711. Firearms; projectiles. INDUSTRIE-WERKE KARLSRUHE A.G. 6 March, 1968 [16 March, 1967], No. 10905/68. Headings F3A and F3C. A firearm comprises a firing tube 1 which receives a projectile 9 the tube 1 being provided with a counter recoil device 11 and being mounted longitudinally displaceably in a guide 2. A stop is provided acting between the firing tube 1 and the guide 2 which stop is disengaged from the firing tube on firing the projectile. The projectile 9 is rigidly connected to a piston 5 which is separable therefrom when, after firing, the piston 5 is restrained by a piston collecting device 8 rigidly fastened in the mouth of the firing tube 1. The piston 5 is connected to the rear member 3 of the firing tube by a holding device 6 which is provided with a fracture point 26. A solid propellent element 23 and a powder charge 24 separated by a foil 42 are housed in the rear member 3 of the firing tube 1, the holding device 6 forming a detonating tube for the solid propellant element 23, which detonating tube is fired electrically from a trigger 15 secured to the guide 2. The counter recoil device 11 comprises a ring of thrust nozzles 40 supplied from a gas supply duct 41 which is covered by a skirt 33 of the piston until the piston has moved a predetermined distance after firing of the firearm. The powder charge 24 may be of the slow burning type to provide the nozzles 40 with a gas flow throughout the firing sequences of the firearm. The piston 5 is deformed when it is arrested in the collecting device 8 (Fig. 5, not shown). The actual recoil of the firing tube 1 may cause the tube 1 to fall out of the cradle.

Title: Improvements in or relating to nuclear reactors
Inventor: ANTILL JOHN EDWARD
IPC: G21C15/28
Filed: 1965-03-15
Abstract: 1,072,745. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 7, 1966 [March 15, 1965], No. 10939/65. Heading G6C. A gas-cooled nuclear reactor has at least some of the surfaces in contact with the coolant of Ni or a Ni-Cu alloy and the coolant comprising CO 2  and a quantity of CO to reduce the oxygen potential of the coolant. In a reactor where the fuel is provided with metallic sheaths, these should be of Ni or a Ni-Cu alloy. At a temperature of 600‹ C., the minimum concentration of CO to give complete inhibition of oxidation is about 0À17% of the volume of CO 2  + CO whilst at 1000‹ C., inhibition is obtained with an addition of about 1À3% CO. With a lower CO content, e.g. 0À8 to 1À0%, some oxidation of the sheaths would occur at 1000‹ C. but the oxidation rate might be sufficiently low to be acceptable. However, other surfaces in contact with the coolant, e.g. in the coolant ducts and heat exchangers, although at a lower temperature than the fuel element sheaths, might also be subject to oxidation and since renewal of these surfaces will not normally be possible, it is desirable to prevent completely the oxidation of these surfaces. These surfaces should also be of Ni or a Ni-Cu alloy. Preferably, to ensure that there is no oxidation, the CO concentration should slightly exceed the minimum required to give complete oxidation inhibition. The strength of the Ni used for the fuel element sheaths may be increased by incorporating oxide dispersions. ThO 2  is most commonly used for this purpose but may not be suitable for nuclear purposes, in which case an oxide, e.g. Al 2 O 3 , of a non-nuclear metal having a low neutron captive cross-section would be preferred.

Title: Improvements in or Relating to Pressure Regulators
IPC: B60T8/26
Filed: 1968-03-07
Abstract: 1,196,988. Fluid pressure brakes. WESTINGHOUSE BREMSEN-UND APPARATEBAU G.m.b.H. 7 March, 1968 [10 March, 1967], No. 11033/68. Headings F2F and F2V. A pressure regulator, for inclusion in the brake pipe between the brake valve and cylinder of an air pressure braking system for a vehicle, includes a differential piston 6, Fig. 1, with a smaller area exposed to the input pressure in chamber 4 than to the output pressure in chamber 14 and an auxiliary piston 5 acted on by the input pressure against the action of a spring 8, the arrangement being such that at input pressures below a predetermined input pressure the differential piston functions independently of the auxiliary piston to produce an output pressure which bears a constant ratio to the input pressure and at input pressures above the predetermined pressure the auxiliary piston and differential piston act together to produce an output pressure which bears a constant, but larger, ratio, than that previously, to the input pressure. As described, for zero braking force, the differential piston is in the position shown with the output chamber 3 connected to the atmosphere via aperture 15. When the brake valve is opened so that pressure is applied to input 2, the differential piston 6 moves downwards until the valve plate 12 closes aperture 15 and valve plate 11 moves away from valve seat 13 in the piston 6 so that the pressure in chamber 4 is communicated to chamber 14. At equilibrium the piston 6 is positioned so that the plate 11 closes valve seat 13 when the pressure in chamber 14 is in proportion to the pressure in chamber 4 in the ratio of the areas of the two sides of the piston. For these pressures the auxiliary piston 5 is held against movement by the spring 8. At the predetermined pressure the input pressure on the auxiliary piston becomes greater than the force on the spring 8 causing the auxiliary piston to be moved downwards until it contacts a stop 9 on the differential piston thereby moving the latter and displacing the valve plate from the seat 13. Above the predetermined pressure, equilibrium is established when the force on the underside of the differential piston due to the output pressure is equal to the force on the upperside of the piston together with the differential force on the piston 5, thus the output pressure is larger in proportion to the input pressure. The regulator is so arranged that at maximum input pressure, the output pressure is equal to the input pressure.
